How do I make a shape key for blink into wink?
Follow the steps below.



In the part where I go into edit mode, the vertices were already selected, but you may have to go into Wireframe view to select the overlapping vertices before doing Blend from Shape

Also notice in the command list under Shape Keys there is a Mirror Shape Key. You could redo the same steps for wink.L and mirror it instead of Blend from Shape to create wink.R
